Every once in a while when I'm using a common unix command, I find myself randomly re-encountering the frame of mind that I was in, the world outlook I had, and the sense of amazement I experienced when I first learned it as a kid. A sudden and explicable feeling awe at the breathtaking pervasive power of "cat" or "ls" or "echo" and how they fit together, and the very idea of a shell with commands and files and directories that you could name, look at, change, and move around. Remembering the excitement of discovering and fitting a new important puzzle piece into the growing model of what I was learning.
